When an electric kettle containing cold water is switched on, the water in it starts boiling after a few minutes. What is the source of the heat energy of the boiling water?

Mechanical energy from the power socket
Newly created energy that increased the total energy
Mechanical energy from the heating element in the kettle
Already existing energy that was present in some other form

straight fertilizers

its 42

i say its d?

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
